Graphing modulus functions - struggling to know what to do

Sketch these curves
y=|x+3|+|x-2|I know you come up with the positive and negative expression for both eg
For x >= -3 … |x+3| = x+3
For x < -3 … |x+3| = -x-3
For x >= 2 ... |x-2| = x-2
For x < 2 ... |x+2| = -x+2So you end up with four different terms. One is the right line, one is the left, then you add two together to get the line that joins them. But I don't know which to use or what to do really.
